Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment 1: A display screen detection device, as Figures 1 - 4 shown, includes a limit frame 1 and support blocks 2 installed at the lower end of the limit frame 1. There are at least two limit frames 1, and the two limit frames 1 are located at symmetric positions. Two support blocks 2 are installed at the lower end of each limit frame 1. Two support blocks 2 at the same horizontal position form a group. One group of support blocks 2 is threadedly connected with a rotating bolt 3, and the threading directions of the two support blocks 2 and the rotating bolt 3 are opposite. The other group of support blocks 2 is inserted with a guide rod 15. A moving column 8 is installed on the outer surface of the limit frame 1. The moving column 8 is inserted with a limit rod 10. Both ends of the limit rod 10 are fixedly connected with a rotating cylinder 11. The moving column 8 is inserted into the rotating cylinder 11 and extends into its interior. A driving motor 12 is installed at one end of the rotating cylinder 11. A detector 14 is installed above the two limit frames 1.

[0026] When the device is running, first rotate the rotating bolt 3. Under the threaded connection between the two support blocks 2 and the rotating bolt 3, they move simultaneously. Based on the opposite thread directions on both sides of the rotating bolt 3, the effect of synchronously and oppositely moving the two support blocks 2 is achieved. Then, under the fixed connection between the support block 2 and the limit frame 1, the limit frame 1 moves synchronously with the support block 2. And under the guiding support of the guiding rod 15 on one side, the two limit frames 1 perform accurate guiding movement, so that the distance between the two limit frames 1 can be adjusted at any time, and it can be adjusted accordingly according to the specifications of the display screen of the mobile phone to be tested. Immediately afterwards, start the driving motor 12. Under the limitation of the limit rod 10 on the moving column 8, its horizontal position is limited, ensuring the reliability of the rotation of the moving column 8 under the transmission of the rotating cylinder 11, so as to simultaneously achieve the effect of rotation adjustment of the two limit frames 1. Then, under the detection support of the detector 14, both sides of the mobile phone display screen can be detected, improving the efficiency and accuracy of the device during detection and use.

[0027] As Figures 1 - 4 shown, a limit groove 9 is penetrated and opened on the moving column 8, the limit rod 10 is inserted into the interior of the limit groove 9, and both ends of the limit rod 10 are installed on the inner wall of the limit rod 10.

[0028] Under the limitation of the distance of the limit groove 9 itself and under the limitation of the limit rod 10, the moving column 8 can move horizontally inside the rotating cylinder 11, and the moving distance of the moving column 8 is limited, ensuring the accuracy and safety of the movement of the moving column 8. At the same time, under the radial limitation of the limit rod 10 on the moving column 8, the rotating cylinder 11 can drive the moving column 8 to rotate simultaneously, thus ensuring the safety and stability of the device during horizontal movement and rotation.

[0029] As Figures 1 - 4 shown, a transmission gear 4 is installed on the outer side of the middle part of the rotating bolt 3. The transmission gear 4 is meshed and connected with a driving gear 5. One side of the driving gear 5 is installed with a rotating motor 6, and the driving gear 5 is installed on the output end of the rotating motor 6.

[0030] Under the driving support of the rotating motor 6 and under the meshing transmission between the driving gear 5 and the transmission gear 4, the rotation of the rotating bolt 3 is accurately controlled, and the transmission gear 4 is arranged in the middle of the rotating bolt 3 to ensure the same and accurate moving distances of the components driven on both sides.

[0031] Embodiment 2: A display screen detection device, as Figures 1 - 4 shown, a support frame 7 is arranged below the limit frame 1. The support frame 7 is rotationally connected with the rotating bolt 3. The rotating motor 6 is fixedly installed in the middle of the support frame 7, and the driving gear 5 is rotatably installed in the middle of the support frame 7.

[0032] Supported by the support frame 7, the operating positions of the rotation motor 6 and the driving gear 5 are ensured to be accurate. The support frame 7 is connected to the rotation bolt 3 in a limited manner. And under the synchronous support of the outer support frame, the accuracy and stability of the driving gear 5 during rotation are ensured.

[0033] As Figures 1 - 4 shown, a support plate 13 is installed at the rear end of the driving motor 12. There are at least two support plates 13, and the two support plates 13 are located at symmetrical positions.

[0034] One end of the detector 14 is installed at the upper end of the support plate 13, and the rotating cylinder 11 is installed on the inner surface of the support plate 13.

[0035] Supported by the two support plates 13 on both sides, the reliability of the operating position of the support plate 13 is ensured. At the same time, the reliability of the rotation of the rotating cylinder 11 on the other side is ensured, improving the overall stability of the device during rotation and further improving the stability of the device operation.

[0036] As Figures 1 - 4 shown, internal threads adapted to the rotation bolt 3 are provided on the inner walls of the two support blocks 2, and no threads are provided at the junction of the support frame 7 and the rotation bolt 3.

[0037] Connected by the internal threads on the inner walls of the support blocks 2, the stability of the support blocks 2 when following the rotation of the rotation bolt 3 is ensured. And under the rotation of the support frame 7 and the rotation bolt 3, it is ensured that the rotation of the rotation bolt 3 will not affect the stability of the support frame 7.

[0038] Working principle: First, rotate the rotation bolt 3. Under the threaded connection of the two support blocks 2 and the rotation bolt 3, they move simultaneously. Based on the opposite threaded directions on both sides of the rotation bolt 3, the effect of synchronously and oppositely moving the two support blocks 2 is achieved. Then, under the fixed connection of the support blocks 2 and the limit frame 1, the limit frame 1 follows the support blocks 2 to move synchronously. And under the guiding support of the guiding rod 15 on one side, the two limit frames 1 perform accurate guiding movement, so that the distance between the two limit frames 1 can be adjusted at any time to make corresponding adjustments according to the specifications of the display screen of the mobile phone to be tested. Immediately afterwards, start the driving motor 12. Under the limitation of the limit rod 10 on the moving column 8, its position in the horizontal direction is limited to ensure the reliability of the rotation of the moving column 8 under the transmission of the rotating cylinder 11, so as to simultaneously achieve the effect of rotating and adjusting the two limit frames 1. Then, under the detection and support of the detector 14, both sides of the mobile phone display screen can be detected, improving the efficiency and accuracy of the device during detection and use.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
